Overview
The 74HCT245PW-Q100J, produced by Nexperia USA Inc., is an 8-bit transceiver with 3-state outputs. This device is designed for bidirectional data transmission and features an output enable (OE) and a send/receive (DIR) pin for direction control. A HIGH on the OE pin causes the outputs to assume a high-impedance OFF-state, making it versatile for various applications. The 74HCT245PW-Q100J is qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1), ensuring its suitability for automotive and other demanding environments.
